Bug#984635: unblock: tqdm/4.57.0-2

[Sandro Tosi <morph@debian.org>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Please unblock package tqdm

[ Reason ]
the last upload of tqdm fixes a RC bug

the effects of that bug are only visible in reverse dependencies, and they were
caused by disabling setuptools_scm during build (as that interferes with our
build process).  That result in a package that would ship a egginfo with version
equals to 0.0.0.

Packages requiring a specific version would fail because that versoin would be
higher that 0.0.0.

the fix was using one of the common practices (documented via a link) of
retrieving the module version from a source file in setup.py, and update the
existing patch for disabling setuptools_scm to include this change.

[ Impact ]
(What is the impact for the user if the unblock isn't granted?)

[ Tests ]
i waited to open this request until all rdeps autopkgtests have completed

[ Risks ]
trivial fix

[ Checklist ]
  [x] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in testing
